Not sure about Legion of Super Heroes...but it will be the Legion of Doom....although with the title, I am certain that is possible... Here is the only write up I could find ...

Cover spoilered for size

I picked this one up. It's a strange amalgam of various DC continuities, somewhat like a modern version of Superfriends but with the New 52 costumes. It does feature the Time Trapper in a somewhat unrecognizable form, my favorite Legion villain, and a couple of Legion alumni like Karate Kid.

A bit disappointed the movie only ran about 53 minutes, the backcover includes a couple of the bonus Superfriends episodes in the overall running time. The animation is a step behind most of DC's recent fare, it looks like it was intended as a TV special meant for Cartoon Network.

I wouldn't worry about this one getting double dipped on Blu-ray, even though it was almost certainly animated at 1080P.
